Some English words can be formed phonetically by
alphanumeric sequences, such as DK (decay) or K9 (canine).
In this puzzle, the eight radial entries, from the rim to
the center, and the horizontal entries 9, 10, 11, and 12
are of this type. However, the circumferential (across)
entries starting at 1, 3, and 6 are "normal" crossword
entries.
